M "LES PIPITONE, OF BROOKLYN, NEW YORK, ASSIGNOR, BY DIEECT AND MESNE ASSIGNMENTS, TO INTERLOGKING CONSTRUCTION CORPORATION, A CORPORATION INTERLOOKING BUILDING- BLOCK.

Application filed Kay 27, 1922. Serial No. 564,189.

To all whom it may concern:

Be it known that I, CILUILES PIrrroNn, a subject of the King of Ital and a resident rookl n, in; the county of Kings an State of ew York, have invented certain new and useful 1mrovements in an Interlocking Building lock, of which the following is a full, clear, and exact specification.

This invention relates to a class of articles of manufacture adapted to be used as a building material.

My invention has for its object primarily to provide a block designed to be utilized for erecting buildings, walls and other structures, and which is molded preferably of cement, commonly known as concrete, in a form so that each block will interlockwith the next adjacent block when a number are erected in a row, the invention also contemplating the provision of a block having an exposed face molded and colored to represent laid brick or various kinds of stone, in order to facilitate the process of erection as well as obtaining the advantages generally resulting from the use of concrete in structures. The block consists mainly of a body part of substantially a rectangular shape having in one of its ends a transverse groove, and on the opposite end of the body part is a transverse extension member disposed on alinement with the groove as well as being smaller than the groove so that when a number of the blocks are laid in a row the blocks are interlocked by the extension members being interfitted in the grooves. On the front faces of the body part and extension member is a plate having projecting spaced sections of formations which may represent structurally erected brick or stone and all of these parts of the block are molded integrally from cementitious materal.

A further object of the invention is to pres vide an interlocking block of a simple, efficient and durable construction which may be made in any appropriate shape and size.

With these and other objects in view, the invention will be hereinafter more fully described with reference to the accompanying drawing forming a part of this specification in which similar characters of reference indicate corresponding parts in all the views, and will then be pointed out in the claims at the end of the description.

In the drawing, Figure 1 is a perspective view of one form of interlocking building block embodying my invention.

Fig. 2 is a sectional view, partly in detail Eaken through the block-on the line 22 ;0

Fig. 3 is a sectional view, partly in detail, taken crosswise through the block on the line 3-3 of Fig. 2, and

Fig. 4 is a fragmentary view, showing in perspective, the manner of interfitting two of the blocks when used in the erection of a structure.

The block has a body part 10 which may be substantially rectangular in shape, and in the central portion of one end of the body part is a transverse groove, as 11, while on the other end of the body part on alinement with the groove is a transverse extension member, as 12. This extension member is of a shape, similar to the shape of the groove which is slightly larger than the extension member. The body part 10 and the extension member 12 are made of cementitious material, such as cement commonly known as concrete of a class extensively used for erecting structures.

On the front face of the body part 10 may be a plate 13 which is also of cementitious material so that the plate and body part may be molded-together when the block is made, and embedded in the block between the body part and the plate 13 may be a plate l t of intersticed or perforated wire or sheet metal to cause the plate 13 to firmly adhere to the body part. The block may be molded so that its exposed face will represent erected stone or laid brick, as illustrated, and to accomplish this the cementitious plate 13 is colored, for example, in red and molded to provide exposed protruding s aced sections 15 each of which is substantial y rectangular as well as being of a size similar to the size of an ordinary brick. The block is preferably made of a size so that the sections 15 are six in number which are relatively dis posed in spaced staggered relation representing three rows the usual form of laid brick, as shown, and one of the sections of the central row terminates at one of the edges of the groove 11, while the second section of this central row terminates at the free end of the extension member 12. Thus when two or more of the blocks are laid in a row, as shown in Fig. 4, the extension member 152 with its brick symbolized face is interfitted in the groove 12 of the next adjacent block,

and by laying rows of the interfitted blocks one upon another a building, wall or other structure may be erected which has the appearance of being laid of brick of the ordinary types.

Also embedded in the block in spaced relation to the intersticed plate 14 is a sheet element 16 which may be of asphalt or other waterproof material for preventing moisture from passing through the pores of the block, and on spaced parts of the intersticed plate 14 may be vertically disposed spaced bars,'-as 17 and 18. Extending from these bars are two rods 19 and 20 which are embedded in the central parts of the body part 10, and these rods are disposed on longitudinal alinement toward the rear face of the body part. On the second end of each of the rods 19 and 20 is a hook or eye 21, and

the hooks are in register as well as being spaced from the rear face of the body part. In the registered hooks 21 of the rods 19 and 20 is a rod 22 of a length so that one of its ends terminate within the extension member 12 of the body part 10, while the other end of the rod 22 terminates at the groove 11 of the body part. Embedded in the upper and lower parts of the body 10 may also be rods 23 and 24 which are disposed above and below the rod 22, thus by the provision of the hooked rods 19, 20, with the rods 22, 23 and 24 the block is reinforced against tendency to easily break or crumble.

In the foregoing description, I have embodied the preferred form of my invention, but I do not wish to be understood as limiting myself thereto, as I am aware that modifications may be made therein without departing from the principle or sacrificing any of the advantages of this invention, therefore, I reserve to myself the right to make such changes as fairly fall within the scope thereof.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1.
